Terminase enzymes mediate genome "packaging" during the reproduction of DNA viruses. In lambda, the gpNu1 subunit guides site-specific assembly of terminase onto DNA. The structure of the dimeric DNA binding domain of gpNu1 was solved using nuclear magnetic resonance spectroscopy. Its fold contains a unique winged helix-turn-helix (wHTH) motif within a novel scaffold. Surprisingly, a predicted P loop ATP binding motif is in fact the wing of the DNA binding motif. Structural and genetic analysis has identified determinants of DNA recognition specificity within the wHTH motif and the DNA recognition sequence. The structure reveals an unexpected DNA binding mode and provides a mechanistic basis for the concerted action of gpNu1 and Escherichia coli integration host factor during assembly of the packaging machinery.

Background The purpose of this descriptive study is to outline the Roseman University of Health Sciences (RUHS) College of Dental Medicines’ Patient Assistance Fund development, organization and outcomes. The description and reported results provide insight to others considering similar health professions programs. Methods The Patient Assistance Fund (PAF) affords dental students an opportunity to petition for and obtain financial assistance for their most disadvantaged patients. In this study, two sources of data were collected and used with a quantitative analysis for data collected as part of the PAFs operation and a qualitative analysis to evaluate the patient experiences. Results A total of 16 student advocates, consisting of 6 males and 10 females from the D3 and D4 classes made 26 presentations to the PAF board committee. The combined amount requested from the PAF was $47,428.00 (“Cost of Treatment Plan”) representing an average request per patient of $1824.15 (range $324.00 to $4070.00). The approved procedures and treatment plans totaled $21,278.36 (“Cost of Approved Procedures”) with an average of $818.40 (range $204.00 to $2434.00) per patient. Patients and students expressed a high degree of satisfaction with the program. Conclusions This study provides an overview of the structure, funding sources, expenditures and patient services supported by a dental student managed patient assistance fund. The experiences at RUHS College of Dental Medicine (CODM) suggest that other healthcare professions schools can develop similar type programs that yield benefit both to students and to patients in need.

In the fourth year of our medical programme, students are required to complete a nine-week rotation in Pediatrics. During the remainder of the academic year students rotate through Obstetrics & Gynecology, Public Health & Primary Care and Psychiatry. The Pediatric course includes a number of assessments: in-course assessments consisting of written reports, presentations, and demonstration of life-long learning skills; clinical skills assessment; a multiple choice question examination; and an OSCE. These many components contribute different percentages to the final results. Previously, this information was manually formatted and distributed. Not only was this timeconsuming, but it was also difficult to present the individual student reports in a comprehensive, timely and transparent way during the examination review board meetings. Limited application tools to manage and present these data were available in the market.
